ANTIFBAUD BOTTLE DEVICE.

Application filed November 15, M312.

To all whom i may concern Be it known that I, ROBERT VALLANon DONALD, asubject of the King of Grreat Britain and Ireland, &c., residing atSkipton, in the State of Victoria, Commonwealth of Australia, haveinvented certain new and useful Improvements in Antifraud BottleDevices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others'skilledin the art to which it appertains to make and use the same.

The present invention relates to antifraud bottle devices and my objectis to provide a simple, inexpensive construction which shall resist to aconsiderable extent attempts to refill the bottle after it has beenpartly or wholly emptied.

In my device the bottle itself has certain modifications whereby toadmit and retain in position a dome, under which is a sealing member.The bottle is to be filled before Ithe dome and sealing members areinserted. These may both be inserted together, the rubber or like edgesof the sealing member being compressed until it has descended as far asa groove which is described later, when it will expand.

In drawings herewith I illustrate a construction preferred though it maybe modified in minor respects while retaining matter which I claim.

Figure 1 is an enlarged sectional side elevation of a bottle neck top,and Fig. 2 is a plan view in section on lines A-B of Fig. 1.

In these drawings 1 represents the bottle neck, with an external annularswelling or thickening 2, and an internal annular groove or recess 3intended to prevent withdrawal of a circular sealing member whichcontains a central valve, and which is made of rubber or like suitablematerial.

5 represents any ordinary cork or stopper which is to be removed whenthe bottle is to be opened, and 6 is a frangible dome of, for example,glass lwith apertures as 7 which are horizontal and lead to or from thedome interior. The dome has an annular recess 8 into which ts an innerannular flange 9 on the circular sealing member which has alsoSpeccation of Letters Patent.

an outer annular flange 1() to enter the bottle neck recess 3.

The base of the sealing member is a ring 11 the outer part of whichrests upon an annular inwardly extending lip or fiange 4 on the bottleneck. The said ring has an inner lip 12 which surrounds a centralaperture or the like through which liquid is to be poured out, the upperface of lip 12 having a recess or being adapted for the contact of theunder side of the edge of the valve which is marked 14 and which will beraised, as illustrated in Fig. 1, by the pressure of liquid in thebottle when the latter is tilted for the purpose of pouring from it.When the liquid is issuing it passes through one or more holes 7 butleaves one or more other holes for the admission of air to the bottle.To hold the rubber or other edge 10 still more fixedly in the bottle alittle cement is at will filled in around edge 16 of the dome thussealing the bottle neck to the sealing member, and also sealing the domein place. The valve 14 forms when closed a temporary seal on edge 12 soas to allow liquid to remain above the valve and help to weight it down.To extend this tendency the valve top may be recessed as at 17 a shallowrecess only being shown, but in practice a pocket or well of muchgreater depth would often be advantageous. Any such well or recess wouldalso serve as a means of detecting attempts to introduce liquids astraces of the latter would be retained therein.

Dotted lines in Fig. 1 show raised position of the valve assumed whenthe table is tilted to discharge liquid.

I prefer that the valve 14 be in one piece, but a distinct valve hingedon as at point 15 could be used and could be of suitable metal. Anysuitable lettering or devices may be printed or put on the dome orvalve, or both, to indicate the manufacturer, or vender, or so on.

Having described this invention, what is claimed by Letters Patent is:-

1. In combination with a bottle neck having an internal recess, a valvering having a flange fitting said recess, an apertured dome having meansfor interlocking With the flange whereby the apertured dome s retained nplace, a valve on the valve ring under the apertured dome, and a Seatfor he valve on said valve ring.

2. In a non-rellable bottle, a bottle having a neck with an annularrecess forming a seat, a valve ring tted in the recess, said t valvering having a valve seat at its Inner edge, a valve engaglng the Seatand an 1n- Wardly extendlng annular flange on the ring, and an apertureddome having an annular recess to receive the annularrlange of the ringwhereby the said Vapertured dome and ring are nterloekngly connected.
